I've been using Vimeo lately to manage video, but I have a client who doesn't want to pay for the plus account, but wants a private video. Any other solutions out there?
It's currently a .mov, and I know we can just throw that in a browser, and it will work in many cases, but will that be compatible "enough", or do we need a more robust solution where we convert the file into an flv, etc.?
You need to start studying the new 'video' and 'audio' tags for html5. They work in Firefox, Safari, Chrome and Opera, I think, but don't recall which versions of each. That's not the current state of the art but the bleeding edge.
You could convert it to FLV, import into Flash (which is pretty automatic) and then embedd it using SWFObject (which will automatically take care of browser and Flash player nuances).
Or you could upload it to Youtube and mark it private ( link ).
Video for Everybody. Requires encoding the video twice, but works absolutely everywhere.
